consonant sound

All consonants are produce by entirely or almost entirely stopping the airstream coming from the lungs. when we almost entirely stop the airstream we force it through such a narrow opening that the airflow at that point is turbulent and noisy.

there are two types of consonants:

VOICE SOUND:

sounds produce when the vocal cords are vibrating.

VOICELESS SOUND:

Opposed to those in which the vocal cords are apart.
